The vapor pressure of pure water at 35°C is 42.2 mm Hg. What is the vapor pressure of a mixture of 7.5 g sucrose (C12H22011) and 42.5 g water? a. 21.8 mm Hg O b. 41.8 mm Hg O c. 35.9 mm Hg d. 40.6 mm Hg O e. 7.45 mm Hg

Based on the graph which describes two liquids, A and B, select ALL of the FALSE statements. XA OA The substance with the higher pure vapor pressure (P") is B OB. The substance with the higher pure vapor pressure (P°) is A OC. For any mixture of A and B (any ratio of A and B), the mole fraction of B in the vapor phase will be larger than the mole fraction of B in the liquid phase. OD. An equimolar mixture of liquids A and B are placed in a closed container (25 °C). At equilibrium, the vapor above the mixture will contain more moles of B than A OE Substance B has greater intermolecular forces than A MacBook Pro esc %23 & 1 2 3 4 5 6 7 8 9. delete Q E R T.

Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.
